使用UNION与LIMIT的MySQL操作指南

Question

所以，我手头有这个问题。

我必须从不同的表中使用内连接获取多个记录，并使用UNION或UNION ALL进行分页，下面的代码是用于获取所有记录和计数的。这是我的宿敌：

(SELECT pp.id as id, pp.*, i.name, p.name as plans_name, u.username,u.email,u.phone, DATE_ADD(pp.init_date, INTERVAL pp.avaliable_days DAY) as end_date FROM property_purchase pp
        inner join users u ON pp.users_id $username
        inner join inn_oficial i ON i.photo_id = pp.property_id
        left join plans p ON pp.plans_id = p.id
        WHERE (pp.type = 1 or pp.type = 2) 
        $where ) 
       UNION 
        (SELECT pp.id as id, pp.*, i.model as name, p.name as plans_name, u.username,u.email,u.phone, DATE_ADD(pp.init_date, INTERVAL pp.avaliable_days DAY) as end_date FROM property_purchase pp
        inner join users u ON pp.users_id $username
        inner join rent_oficial i ON i.photo_id = pp.property_id
        left join plans p ON pp.plans_id = p.id
        WHERE pp.type = 3
        $where) 
       UNION 
        (SELECT pp.id as id, pp.*, i.name, p.name as plans_name, u.username,u.email,u.phone, DATE_ADD(pp.init_date, INTERVAL pp.avaliable_days DAY) as end_date FROM property_purchase pp
        inner join users u ON pp.users_id $username
        inner join fish_pay_oficial i ON i.photo_id = pp.property_id
        left join plans p ON pp.plans_id = p.id
        WHERE pp.type = 4
        $where ) 
       UNION 
        (SELECT pp.id as id, pp.*, i.name, p.name as plans_name, u.username,u.email,u.phone, DATE_ADD(pp.init_date, INTERVAL pp.avaliable_days DAY) as end_date FROM property_purchase pp
        inner join users u ON pp.users_id $username
        inner join stores_oficial i ON i.photo_id = pp.property_id
        left join plans p ON pp.plans_id = p.id
        WHERE pp.type = 5
        $where)
       UNION
        (SELECT pp.id as id, pp.*, i.name, p.name as plans_name, u.username,u.email,u.phone, DATE_ADD(pp.init_date, INTERVAL pp.avaliable_days DAY) as end_date FROM property_purchase pp
        inner join users u ON pp.users_id $username
        inner join transfer_oficial i ON i.photo_id = pp.property_id
        inner join plans p ON pp.plans_id = p.id
        WHERE pp.type = 6
        $where)
        GROUP BY pp.id
        ORDER BY pp.id

我从13.2.9.3 UNION Clause中获取了这个例子，并在脚本上尝试了一下

当我尝试运行代码时，它报错了

在第1行的'GROUP BY id ORDER BY id LIMIT 0.25'旁边，你的SQL语法有错误

对不起，我的英语很糟糕，这不是我的母语

Answer 1

我解决了 ksskskskks，只需将 pp id 列添加为 id_p，然后按该排序
